A right-wing Arizona congressman known for his hardline immigration stance and faith in conspiracy theories wants the feds to check IDs at the State of the Union and bust any undocumented immigrants who try to attend.

“Of all the places where the Rule of Law needs to be enforced, it should be in the hallowed halls of Congress. Any illegal aliens attempting to go through security, under any pretext of invitation or otherwise, should be arrested and deported,” GOP Rep. Paul Gosar wrote on Twitter.

More than two dozen Democratic lawmakers and one moderate GOP rep have invited Dreamers — young people brought to the US illegally who had been protected from deportation by the Deferred Action for Childhood Arrivals program — to attend President Trump’s first State of the Union address.

People protected by DACA are in the US legally and are not subject to arrest simply for being here.

But Gosar, according to The Hill, asked the Capitol Police and Attorney General Jeff Sessions to consider checking the identification of everyone attending and arresting any undocumented immigrants they find.

Gosar has been in the news before, once suggesting that the deadly white nationalist and neo-Nazi rally last summer in Charlottesville, Virginia, was a false-flag operation cooked up by an “Obama sympathizer” and funded by George Soros, who Gosar said “turned in his own people to the Nazis,” according to Vice News.

Soros, the liberal billionaire, escaped Nazi-occupied Austria in 1944, when he was 14.

Gosar, a dentist who represents a largely rural area of the Copper State, was also the lone lawmaker to skip Pope Francis’ address to Congress — because he was going to talk about climate change and not “violent Islam.”

And he’s a fierce anti-marijuana advocate who has also insulted his state’s Native Americans by dismissing them as “wards of the federal government,” according to multiple reports.

Rep. Carlos Curbelo (R-Florida), a moderate running for re-election in a district Hillary Clinton won in 2016, is the only Republican bringing a DACA recipient as his State of the Union guest.
